DRIVE-GEAR FOR AUTMOBILE S.

Pat-einen Mar. 14, 1916.

vReferring tothe drawings, there is shown a portion of a 4vehicle frame having side bars l, usually constructed of channel metal, and so shown in the drawings, although of course the frame may be otherwise y constructed. Connecting the 'side bars at one point is a cross bar, 2, and'at corresponding to the rear end Attached to the elevated portioni of each side bar is a spring element 5, which. in turn is connected to the side bar 1 by means of a bracket 7 or in any other suitable manner. The invention has nothing to do with the particular type of spring, vand so it will be understood that any suitable form of spring may be employed. y

In the drawings are shown wheels S, which in their general construction may follow the conventional forms employed in automobiles., rEhe wheels each have an axially .elongated hub 9, on which they are secured. Each hub adjacent to the wheel thereon is formed with a brake drum 10 comprising a radial flange 11 andan overhanging marginal iiange 12. The iiange 11 provides an abutment for a circular angle member 13 having a web surrounding the hub 9,. and a ring-shaped yface plate 14 between which and the angle 13 the spokes of the wheel and face plate to the brake drum 10. Each hub 9 is mounted upon a corresponding end ,of an axle 17, which inthe particular show,

Each hub 9, between the roller bearings, the hub beinghollowed out forl the accommodation of the bearings, 18, is provided with an axially elongated external grooveor channel 19 for the reception ofroller bearings 20, to which reference willhereinafter be made. The 'outer end of` each hub is farmed with a ballffiirace for anti-friction :balls 21and these balls are held in place by a cone 22 and nut 23, `the latter' being ho sed by a cap nut 24 appli/ed to the outer end of thehulm n v That end jof th hub reinste from the nut y 'sa radialr flange ,25fhaying re. v'side remote from-the a taee'haer'a marginal VArabbet l26.

members 30, each member being preferably` integral with the axle and of an internal diameter greater than the exterior diameter of the gear wheell 27. Secured to the mar- "ginal portion of each casing member 30 is another casing member 31 formed of two half members provided with 4branching flanges 32 by means of which the two half members are secured together by bolts 33 The casing member 31 has an axiallyextended tubular prolongation 34 of a size to receive the corresponding part of thehub v9 and to inclose the rollers 20,

holding them in the channel 19'. A, dust lcap 35 applied to that end of the tubular extensionl 34 remote from-the casing member 31 serves to protect the rollers 20 and the in-A terior of the casing from access of dust and also the parts are so constructed that the 25 and acting in opposition to `ings 21. yThe two ball bearings 21 and 37 vided will retain lubricant `without leakcasing I age. The ,outer wall of the casing 30 is prowith ball races 36 containing antifriction balls 37 bearing against that face of the gear wheel'27k remote from the flange the ball beartake up all end thrust` and mat `tai A-the axle in proper position with a minimum of friction. e v i The casing members 30 Aand 31.are cutoff on one vsidealonga chord. and to this chord portion therel is sccuiiral a hollow cap 3S,the

feasible to employ v ordinary roller bearings,

cap being suitably flanged as'shwn at 39,l

and abutting like flanges of the /fcfasing members and 31, respectiiely:l At one side the casing member 38 is formed ywith a bearing 41 for a vcounter shaft section 42, and on the other side thecasingBS is formed with another bearing .43 vfor the counter shaft section 42. fWithinthe 'cap 38 the shaft section 42 carries a pinion 44 fast thereto and in-mesh with thegear wheel 27.

The structurel includes two hubs 9 and two casings 30-'and 31 in spaced relation, and each casing has a cap 38. The member 43 of each cap has an axial prolongation 45 terminating in a half casing 46. said .casing members 46 joining at the longitudinal mid line ofthe vehicle, and such casing incloses- .a differential gearing which ymay' follow` the usual lines of differential'gearing, therefore,

' no attempt is made to illustrate it. Each counter shaft section 42 'is extended outwardlylbeyond the bearing 41, and there -carr1es"a brake drum 47 which may be employed as supplemental to the brake.

drums 10. v

The'casingllG carries a bearing 48 for a drive shaft 49` ,extending through a tubular casing 50 fast to the bearing- 43 and continued forwardl)v toward the customary7 location of the driving engine. The shaft 49 terminates atthe end remote from the bearing 4S vin a squared end 50i1 or other non-circularextension Ventering and bearing in'a knuckle or universal connection 51- to a drive *shaft section 52 inl turn having a' knuckle connectionv to the `main drive shaft 54 of the engine.

The casing 49 is slidably mounted in a vsleeve 55 having trunnions 5G 'at 'opposite sides mounted in' gears 57 of a bracket 5S. which latter lismade fast to the cross beam 2 at apoint about midwa)v of its length.'

Applied to the casing 50. which is alilocated at about the same-height as thc axle 1T. the shaft 49 and casing 50 will have a vcertain degree of inclination. lThis may be eliminated b v locating the counter shaft 4'. at a higher point than illustrated inthe drawings. in which case the ii'iclination `ot' the shaft 49 and cas-ing 59 is correspondinglv less and thc transmission of power is more ncarliv in a direct linc from the 'engine to the diil'cicntial gearing within ,the caff' ing 4U.' f f lflach extension 34. where surroundingr thc `bearing rollers 20, is formed with oppositely directed tangential flanges 62 constituting-1a plate lwhich receives the corresponding spring 6. On the opposite face of the spring 5 6 there is applie d"another plate 63 connectedto the collar 6- by U-bolts 64, as is 'customary in springfastening structures.

Located v4,on tlieplate G3 is a post 65 tei minating "verhanging' portion v66 designedftl one end of av brake i the respective brake ,5,- strap `is ap ropri ception `of nia'nipulating means.

Those portions of the casings 30 and 31 remote from the capBS are joined by a connecting rod (S9. `Extending from each cap 38tovvard the casingvOii's-a brace member 70, which may be of tubular form," as shown, or maybe otherwise constructed, each brace A70, at the end` remote from the'respective c'ap 3 8, is made 'fastat the end remote from the capto a lug 71 of a clip 7:2 fast to the casing 50, between the bearing '48 and the adjacent nut 59. y I

The casings SOand 31, with the'jcaps 88 and the extensions 45, together 'fvvith the diferential casing 46,- form receptacles 'for lubricant, so that moving parts are'at all times maintaine tion. l Y

The power applied'tothe shaft 54 causes a rotation of the shaft member 52, and the sha-ft 49 through the knuckle joints 53 and 51, and this power is transmitted through the usual differential gearing housed in the casing 46 through the counter shaft 42 and from the latter by the pinions 44 to the gear Wheels 27,` \vhich gear Wheels, being fast to the respective hubs 9'. produce rotation of the drive" Wheels 8.

The casings 30 and 31 inclosing the respective 'gear Wheels 27 are located in the y space betvveenthe side bars 1 andV hence .are 45 supported quitea distance from thedriving Wheels, ,'so that mud and dust lifted by the drive 'Wheels and' thrown' about 'b v. said drive Wheels are not liable to reach the casings. `Even if some such deleterious matter shouldreach thecasings, access to the casings isprevented b v very tightconstruction, such inaccessibility being very diicult if not impossible of accomplishment Where the gear Wheels are made fast to the hubs closely adjacent to `the driving Wheels.

Moreover, the axiall prolongation ofv the i hubs, which prolongation is 4unich in excess of the usuallengthsof the hubs, permits Vthe employment of axially sepa1a ted.bearings, so thatordinarylroller bearings may be employed instead of much more expen-y sive ,special bearings. I' p The'pro'longotion of the casing members 31 in the-form of a neck 34 provides for the support of the springs upon such c asmgs,

Moreover, ythe .axle serves as a connecting mehr: ber, and has the support/for the casings inclosing` the gearing,` and such casingsare made specially rigid by the connecting bar or rod 69 and the -bracerods 70. i

-Variations in position'otthe frame with respect to the drive Wheels andgto the drive shaft is compensated by.'tliev-rockingrsupport represented by the sleeve 55, while vlongitudinal movements of th'efcasingvO `with frame are eased and'taken up by they springs 60, which latter serve to-centralize thecasingvO lengthwise of the vehicle. Moreover. by disconnecting the springs `from the ihub4 casings, and disconnecting the shaft .49,from the engine shaft, the Whole rearvvheel structure may be readily removed from theavehicle for inspection orrepair or .toyr'l any other purpose. The Ibrace rods 70 vin no Wise interfere with rising and falling ofthe casing 50, but serve to steady thegear casings 30 and 31, andthe faxle 1T and vWheels- St against, twisting or side movements, While the structure of .the ,presentl inventionis particularly adaptedforA use `in connection with automobileS, and has beenv so; described.

it will be understood `that` the invention part may be used v and the ter'nrautostood as covering any appropriate vehicle.

While the casing members SOvare'. slio'unas piece with the-.axle 17, it ivil'l'be `understood thatthe-beneiits o'fvsuchconstruction may be accomplished by'shrinking said: k115` vcasing members on the axle.

lVhile it has been stated,that-tl1e`di1`teren.l

tial gearing employed isnt/customary construction, it will be "understood thatlbecfause of the introductionofthegeariug between the counter shaft and the hub4` the direction of transmission of lmotion through lthe differential gearing must be reverse from the direction of Imotion in structures where the is mounted directly onv the axle.
